I see two major issues here; first and foremost is denial. Yes, there is a problem, and if you can't see it, it's probably because you are part of it (and almost certainly a male). It's like how whites in the South think that racism isn't a problem anymore. This *needs* to be addressed, and the first step is admitting there is a problem. As for dealing with the problem itself, I can say that part of it is the whole "brogrammer" phenomenon which has cropped up in recent years. I can say unreservedly, brogrammers need to fuck off; they are not welcome, and if they won't police themselves, we will. Hacker culture is one that should, above all else, respect intellect and creativity; gender, oneupmanship and "frat" antics don't come into it at any point.
The second issue I see is that the answer to the article question is no, sexual harassment is not a part of hacker culture. If sexual harassment is happening, it needs to have a bright light shone upon it, like a software bug, so that it can be fixed. We need to not allow these broken windows to exist in our house. The perpetrators should be shamed and banned from conferences, at a minimum. Some of the anecdotes I've heard would warrant criminal charges being pressed. The New Atheist movement is having similar issues, and they are starting to respond by banning people. If you think this is "censorship", fuck off; you can get your own fucking website and post all the misogyny you want, but you can't force others to host it for you.
I went to university with Valerie, and she's very smart, probably smarter than a lot of people here (definitely smarter than the knuckle-dragging, mouth-breathing, misogynistic brogrammers who have infested the computer industry). She's been writing and talking about this problem for long time; it would be wise to listen to her.
One last point: I'm not "disgusted" or "offended" by these acts; I consider them the vulgar acts of those not fully human (for they lack empathy) and therefore beneath my contempt. These people should be treated like the animals they act like, and kept out of hacker culture so that we can get on with real work.
